Washington Post: Rapist's Trail
The Washington Post have produced an impressive interface to explore the story of a rapist believed to be responsible for 17 attacks in Maryland, Virginia, Connecticut and Rhode Island.
The story includes a large custom produced interactive map showing the locations of each of the attacks.
The application also makes effective use of a small Google Map for its details on each individual case.
Website Innovative Interactivity has an interesting interview with Kat Downs, Information Designer at The Washington Post, about her experience designing and building this impressive interface. The interview includes a brief explanation of some of the design issues of using Google Maps in the interface.
